Mark Twain said this quote

Look at the tyranny of party-- at what is called party allegiance, party loyalty-- a snare invented by designing men for selfish purposes-- and which turns voters into chattels, slaves, rabbits; and all the while, their masters, and they themselves are shouting rubbish about liberty, independence, freedom of opinion, freedom of speech, honestly unconscious of the fantastic contradiction; and forgetting or ignoring that their fathers and the churches shouted the same blasphemies a generation earlier when they were closing thier doors against the hunted slave, beating his handful of humane defenders with Bible-texts and billies, and pocketing the insults nad licking the shoes of his Southern master.
